Snow squalls for the west
Hazardous Weather Outlook issued 439 am Fri Nov 29 by NWS Binghamton
There is potential for snow showers or squalls across portions of Central New York today into this evening. As temperatures drop later this afternoon, the snow squalls will lead to rapid drops in visibility and hazardous road conditions.
Lake effect snow could impact the region beginning Sunday night and lasting into early next week. There is a potential for significant snow accumulations. If you are planning travel early next week, monitor NOAA Weather Radio, social media or your favorite media outlets for the latest information, forecasts and warnings.
Weather spotters are encouraged to report significant weather conditions according to Standard Operating Procedures. Please relay any information about severe weather to the NWS.

Streamflow Situation from the network of USGS monitoring sites in NYS
Provisional data from a streamflow gauge in Great Kills Harbor indicating major flooding this morning has been addressed by the USGS. Personnel have confirmed the reading more than five feet above major flood stage, now investigating the operational status of the station. As of this update, the sensors at Great Kills Harbor show water level below minor flood stage.
Overcast, 44 degrees with a chance of sprinkles in NYC. Cooler air is moving in today for the weekend, be prepared.
Normal to above normal streamflow levels in all but the Lower Hudson River watershed, still below to much below normal. Drought ratings have come off much of the map overnight with the new precipitation refreshing the watersheds. Upper Lake Champlain is stepped back to moderate drought from severe drought, below normal ratings remain in Chemung River watershed in the south, St Lawrence River watershed in central St Lawrence County and Lower Hudson River watershed in all but Ulster, Dutchess and Orange Counties, unrated. As of this report, there is one station indicating flooding, Great Kills Harbor running above 13 ft, this value is extreme and presumed to be a sensor error. More to follow. There are two low flows in the network at the 3rd percentile, both are in the Lower Hudson River watershed on the east side, the Croton River drainage area.
The FEMA Flood Map Service Center (MSC) is the official public source for flood hazard information produced in support of the National Flood Insurance Program (NFIP). Use the MSC to find your official flood map, access a range of other flood hazard products, and take advantage of tools for better understanding flood risk.
FEMA flood maps are continually updated through a variety of processes. Effective information that you download or print from this site may change or become superseded by new maps over time. For additional information, please see the Flood Hazard Mapping Updates Overview Fact Sheet

WT HAB Tracker from the National Centers for Coastal Ocean Science (NCCOS)early detection program
According to the federal sponsored early detection program for cyanobacteria, NCCOS describes the problem, "Harmful algal blooms (HABs) occur when algae—simple plants that live in the sea and freshwater—grow out of control and sometimes produce toxins harmful to people and animals. Only a small number of species have the capacity to form harmful blooms, but when they do, the effects can be severe for coastal resources, local economies, and public health. HABs occur in every state, and new HABs have emerged in recent years, adding new threats to regions already impacted. NCCOS conducts and funds research that helps communities protect the public and combat blooms in cost-effective ways, and we are breaking new ground in the science of stopping blooms before they occur."
The latest upload of Lake Champlain is dated November 27, a partially cloud obscured image with no HAB activity observed between clouds. The early detection program for HABs from satellite monitoring indicates where State and local authorities may want to sample the water and post beach advisories for detected cyanotoxins, harmful to swimmers and waders, anyone coming in contact with cyanobacteria can be impacted with skin and gastrointestinal symptoms. The toxins damage vital organs, most common microcystins affects the liver. Dogs are especially sensitive to this toxin, testing and posting the impacted water is critical to public safety.
See our final HAB report for the 2024 season, including an alphabetical list of the impacted water bodies, the date of first appearance of bluegreen confirmed and the total HABs for the water body this year, here.
Safe Drinking Water Advisories
Onondaga County: Part of the Town of Elbridge along with Elbridge Village and Village of Jordan were under a boil water order last weekend after County Health determined an issue of inadequate disinfection in the municipal water system. Private wells are not affected. Village of Elbridge Water System is one of 87 SDWA active drinking water facilities in Onondaga County. The system serves potable water to 1519 customers from a surface water source, purchased from another licensed drinking water facility in the Oswego River - Finger Lakes watershed. The facility has had non-compliance issues in 12 out of the last 12 quarters, including monitoring and reporting violations under the Lead and Copper Rule dating back to 1995, unaddressed as of the latest reporting cycle. Several instances of Treatment Technique violations of Surface Water Treatment Rule are noted, these have been resolved.
